STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 223,531, dated January 13, 1880.

Application filed November 1, 1879.

To all whom it may concern I screw-thread that portion of the shank which Beit known that I, STEPHEN S. NEWToN, of enters the plug. But this screw-threading Binghamton, in the county of Broome and may not be essential, as the wire will be held State of New York,have invented certain new firmly in place by friction, care being taken 5 and useful Improvements in Bottle-Stoppers; that it shall be ofsuch size as to fit tightly in and I do hereby declare that the following is a the hole which is formed for its reception in full, clear, and exact description of the inventhe plug; or, when preferred, the shank may tion, which will enable others skilled in the art be made of smaller wire doubled upon itself at to which it appertains to make and use the the center to form theloop G, and properly 10 same, reference being had to the accompanying twisted, so that the two strands shall be seated drawing, and to letters of reference marked in the plug, where they may be held by fricthereon, which form a part of this specification, or by glue or .some other adhesive subtion. stance. I

The object of my invention is to produce a From an examination of the drawing it will 1 cheap, convenient, durable, and effective botbe readily seen that this stopper is especially tle-stopper and sponge-support adapted speadapted for use in bottles which contain liquid cially for use in connection with bottles conblacking, or anyother material which is formed tainin g liquid blacking and to this end it 0011- in part of an adhesive substance, because, sists of the combination of a wooden plug havamong other reasons, the elastic nature of the 2o ing an external groove or circnlarseat,in comwasher B renders the withdrawal of the stopbination with a rubber annulus or packing fitper from the bottle comparatively easy, even ting tightly within the groove and a metallic though it shall have remained so long that the stem adapted to carry in its lower end a sponge contents of the bottle have partially dried at or its equivalent. that point where the washer is in contact with 2 5 In the drawing, which is a vertical section the neck of the bottle, from the fact that as of my improved stopper and sponge-support, a person pulls upon the wooden plug the an- A A is the wooden part or plug, the part A nulus or ring will yield in such manner as to being constructed by preference with a notch gradually withdraw it from the inside of the at its upper end for convenience in grasping, neck or throat of the bottle, commencing at 0 and being also expanded centrally to cover the lower edge-of said washer.

and hide from view the neck or mouth of the I am aware that a bottle-stopper has been bottle, and also to guard against accidental used consisting of a central plug with a groove contact of the hands of the operator with the substantially like that shown at a, and having neck of the bottle, which is apt to have blacka rubber annulus or packing-rin g seated in the ,8 5 3 5 ing adhere toit, which, wereit not for this progroove; but I believe I am the first to employ tecting flange, would be liable to soil the fina wooden plug in combination with a rubber gers of the person using the blacking. ring and a metallic shank for supporting the I prefer to make the lower part of the plug sponge, and the use of a wooden plug in such tapering, as at A. combination possesses many advantages over 0 40 a is a groove formed in the plug immedia plug formed of any other material, because, ately below the flange a. B is an annulus or among other things, it is especially adapted ring formed of vulcanized rubber, of such size for receiving and holding the wire shankthat it shall be held firmlyin the groove by eithera screw-threaded shank, like that shown reason of its contractile strength, and shall in the drawing, or a shank of such size as to 5 5 also be of such external diameter as to fit be driven tightly into a hole formed for its retightly the neck of the bottle. G O is the ception in the plug, and thus held by friction, sponge-supporting shank, formed preferably or a shank formed of twisted wire and held of a single wire, one end of which is bent into firmly in a hole in th'e'plug, either by friction a loop, G, to receive the sponge D. The upor partly by friction and partly by the use of :00

lowerendof the woodenplug,andbypreference I am aware that a tapering wooden plug provided with a circumferential groove having a rubber annulus seated therein is shown in patent to Ames, January 21,1862; but his rubber is in the form of a long thin sleeve, which operates in a manner essentially different from mine, as follows: My washer projects so far from the side of the plug that, owing to the flexibility and elasticity of the rubber, an up- Ward pull on the plug will draw up the inner portion of the washer, and thus draw its lower outer edge away from the bottle by pulling it upon a, line substantially at right angles to the axis of the plug. This feature of construction and operation adapts the stopper especially for usein that class of bottles which contain liquid blacking and similar sticky substances.
